you're not using boost control of any sort and tee-ing off the compressor outlet.........

is your valve cover PCV port just open to atmosphere on both side? That seems like a fire just waiting to happen to me. You’re probably getting some wastegate flex with that mounting solution. My car feels very lazy on just wastegate spring. It’s only like 6psi and I don’t see that until 4K rpm or so. Get some sort of WG control on the car. Also that crunched downpipe isn’t doing you any favors. The 1.6 has a great oil feed on the block you can use and right next to it is a water feed, which looks like you choose not to even water cool the turbo. Kinda questionable but I’ve seen people do that after cracking a feed line on track. |
both should be off the IM. that's for starters.
it seems to me like you made some incorrect assumptions and now puzzled over a problem that you created |

Basically an fm kit.
Looks to me that your wastegate rod is too long. That can hurt spool. And/or some sort of boost control as others have mentioned. |

Thats what i would be thinking, wastegate isnt holding shut as tight as it needs to be. Looks to be some slip in that rod. Try tightening, or spacing wastegate bracket with washers.

Do a test, unhook the WG signal line and see if spool improves. Be careful as there will be no boost control but this will tell you if your losing spool through the wg cracking open early.

That's a good test, but set your overboost to 5psi
|
Already did that, spool is slightly faster. Boost controller is ordered as well so maybe i can use the bottom port on my wastegate to keep it shut. |
Anybody have any logs to post up with their respective setup? have always been curious about 1.6 spool with different manifolds and exhausts despite everybody sh!tting on it for being inferior to the 1.8.
I'd really like to see a journal bearing 2560 vs a BB 2560 as well. next time i have my car out i'll try to grab a 4th gear log. i've always kept my eye on the spool data thread but it's obviously very 1.8 dominated. |
See the "I want your spool data" thread already in existence.
